JRH72N; Single phase, 220-240V, 50 Hz. (Failure to heed this warning may result in
fire or electrical shock.)
•
Install this product in an environment where the temperature ranges from -10 °C
to +46 °C and the relative humidity is less than 80%. If condensation is expected
to form, heat up the fresh outside air by a duct heater etc.
•
Select a position for introducing the outside air where no exhaust or combustion
gases will be sucked into the fresh air duct and where it will not be covered by
snow (Failure to ensure a supply of air can result in producing a state of Oxygen
deficiency inside the room.)

laths or metal, these ducts must be installed in such a way that they will not
make electrical contact with metal laths, wire laths or metal sheets.
(Power leakage can cause ignition.)
•
The outside ducts must be tilted at a gradient(1/30 or more) downwards toward
the outdoor area from the main unit, and properly insulated. (The entry of rain
water may cause power leaks, fire or damage to household property.)
•
Gloves should be worn during installation.
(Failure to heed this warning may result in injury.)
